Abstract-Classification of short stories category based on age of the reader is still difficult. Therefore, a decision support system to classify the short stories category is needed. Naïve Bayes is one of methods suitable for short stories classification. However, Naïve Bayes has flaws in accuracy level, and needs to be optimized. In this paper, Genetic algorithm is proposed to increase the level of accuracy. In this case, genetic algorithm is used for feature selection. The results show an increase in the level of accuracy produced. The accuracy increases from 78,59% to 84,29%. In conclusion, the application of genetic algorithm on Naïve Bayes in classifying the online short stories category can improve the accuracy.Intisari-Penetapan klasifikasi kategori cerpen yang sesuai dengan keinginan, yaitu adanya kesesuaian jenis cerpen yang dibaca dengan usia pembaca, masih sulit dilakukan. Hal ini menjadikan perlu adanya pendukung keputusan untuk dapat mengklasifikasikan kategori cerpen sehingga jenis cerpen tersebut sesuai dengan kategori pembaca. Naïve Bayes merupakan metode yang sesuai untuk digunakan dalam klasifikasi kategori cerpen. Naïve Bayes masih mempunyai kekurangan dalam tingkat akurasi yang dihasilkan, sehingga perlu adanya optimasi. Algoritme genetika sebagai algoritme optimasi merupakan metode yang diusulkan untuk meningkatkan tingkat akurasi yang digunakan. Dalam hal ini, algoritme genetika digunakan untuk feature selection. Hasil yang diperoleh memperlihatkan adanya sebuah peningkatan akurasi, yaitu dari 78,59% menjadi 84,29%. Dengan demikian, dapat disimpulkan bahwa penerapan algoritme genetika pada naïve bayes untuk klasifikasi kategori cerpen online dapat meningkatkan akurasi.Kata Kunci-klasifikasi, kategori cerpen, Naive Bayes, algoritme genetika.I. PENDAHULUAN Indonesia merupakan negara yang memiliki berbagai macam budaya dan kultur yang beragam, seperti halnya dalam penciptaan karya sastra, sehingga tidak heran apabila setiap daerah di Indonesia mempunyai karya sastra yang beragam. Cerpen adalah sebuah karya sastra yang sangat disukai oleh semua orang, terutama di Indonesia. Institusi pendidikan pun pada proses pembelajaran yang dilaksanakan di sekolah memberikan materi yang terkait dengan cerita pendek. Hal inilah yang memberikan motivasi kepada setiap orang untuk dapat membuat sebuah cerpen sesuai dengan keinginan dan inspirasi yang muncul dari penulis. Saat ini penulisan cerpen masih didominasi oleh para remaja dan anak-anak, sehingga tidak heran apabila cerpen yang muncul sekarang ini sudah banyak dari lintas generasi baik itu ditulis lewat buku, majalah, blog pribadi, maupun media online serta situs website yang menyediakan cerpen online yang menyajikan kumpulan cerpen yang dikirim oleh penulisnya.Sebuah karya sastra mempunyai dua unsur pokok di dalamnya. Yang pertama adalah unsur intrinsik, yaitu unsur dalam sastra yang ikut memengaruhi terciptanya karya sastra yang terdiri atas tema dan amanat, alur cerita, penokohan atau perwatakan, latar, sudut pandang, dialog, dan gaya bahasa.

The Internet era has had an impact in various sectors of human life. One is the economic sector. Economic transactions change from the traditional pattern (face to face) to online. The customer does not need to ask about the condition of an item to be purchased to a close friend or family, but simply by reviewing the product from the same buyer's comments. Products that get good reviews mean good quality. However, a problem arises if the comment data is very large and will make it difficult for customers to summarize the quality. Therefore, an automatic opinion mining system is required which can directly give conclusions about the quality of a product. This research makes an opinion mining system by applying the Naïve Bayes algorithm by taking a case study of facebook account Dugal Delivry. The measurement result with confusion matrix gives precision value of 88,89%, recall 80% and accuracy equal to 85%.
Artificial Intelligence is defined as intelligence exhibited by an artificial entity. Intelligence was created and put into a machine that can do the job as do humans. Some kinds of fields that use artificial intelligence include fuzzy logic, expert systems, computer games, neural networks and robotics. The purpose of research is Applying the theory of fuzzy logic in the manufacture of robot control and create teaching materials for the subjects of physics, especially on the concept of a microcontroller or other allied subjects of the research conducted. In this study apply fuzzy logic on the movement of wheeled robot control where in the controlling controlled via a smartphone which is then processed by a microcontroller Arduino that has grown the program by applying the method of fuzzy logic rule. Then by the microcontroller is used as a command to drive the DC motor as a navigation system that course in accordance with the rules created. Every step of the control system provides a signal in the form of a large steering angle (θ) which guides the robot to the target of a starting position. The results showed that the application of a system of fuzzy logic can be implemented in a navigation system for a robot control and the results of testing the robot's movement, then obtained some data points specified coordinates with the coordinates of the control robot acquired a 96% accuracy rate.
